Abstract
543,649. Typewriters. WANDERER-WERKE AKT.-GES. Sept. 2, 1940, No. 13725: Convention date, July 18, 1939. [Class 100 (iv)] Letter-spacing mechanism.- Mechanism for increasing or decreasing the spacing movements to obtain a justified line, is set in accordance with the line deficit or excess, and the length of the line by means of two setting-members such as knobs which can be manipulated from the front of the machine. In the mechanism shown in Figs. 2 and 3, a rack 304, co-operating with escapement-mechanism 326, has pin- and-slot mounting 306, 307 on the paper-carriage 320, and is provided with a flange 330 carrying a roller 332 which engages a cam 305 pivoted on the carriage. A pinion 316 on the cam cooperates with a rack 315 on a slide 334 which is mounted on the carriage and is connected by a link 344 to a bell-crank 343 mounted on the carriage. A roller 302 on the bell-crank runs on a rail 301 which is pivoted at 350 to the framework 322. The rail is connected to a link 319 having a pin 354 engaging an arcuate slot 356 in a lever 308 having a roller 357 co-operating with a notched cam 309 on a shaft 359 provided with a knob 313. The link 319 is connected to a bell-crank 311 provided with a roller 363 co-operating with a cam 310 on a tubular shaft 361 provided with a knob 312. In operation, a trial line is typed to determine the space excess or defect, and the knob 313 is then set accordingly by the aid of a scale 314 to raise or lower the rail 301 and thereby cause the cam 305 to decrease or increase the spacing movement of the paper-carriage. To adjust the mechanism for different lengths of line, the knob 312 is set by the aid of a scale 365, and the link 319 is thereby adjusted in relation to the lever 308. To facilitate determination of the number of spaces excess or defect in a trial line, a pointer on the paper-carriage reads plus or minus graduations on a margin stop.
